How to use Perl’s ternary operator
The Ternary Operator
The ternary is actually a sequence of operators. The operator is used like this:
CONDITION-PART ? TRUE-PART : FALSE-PART
which is shorthand for the following statement:
if (CONDITION-PART) {
TRUE-PART
} else {
FALSE-PART
}
Example: If $firstVar is zero, then assign $secondVar a value of zero. Otherwise, assign $secondVar the value in the first element in the array @array.
$secondVar = ($firstVar == 0) ? 0 : $array[0];
